' LEO 1. O'EILEY To all whom it only concern:

Be it known that I, Leo J. ORILEY, a citizen of the United States, residing at Grand Rapids, count of Kent, State of Miehigaxi,

.5 ave inven certain new and useful Improvements-in Phonographs, of which the following is a specification.

This invention relates. to improvements in phonographs. I The mam objects of this invention are:

- First,to rovide an improved phonograph by which a l tones are very accurately reproduced.

Second, to provide an improved phono-' graph in which the tones produced are of great carrying power and at the same time without hars ess or mechanical sound.

Third, tov provide an. improved horn for phonographs. Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my inve tion by the devices and-means described the following specification. The invention is clcarlydefined and inted out in the claims.

structure whic is .a preferred embodiment of my invention is clearly illustrated in the accompan ing draw ,'f0rming a 80 part ofthis spec' cation, in w fiichz j Figure I'- is a vertical central section on a line corresponding to line 1--1 of Fig. II of a structure embodying the features of my invention, the tone arm, record and parts of the motor being shown in full lines and more or less conventionally.

. showing the arrangement-of the bottom'wall parts. Y Fig. VIII is a detail longitudinal section through the top'wall of the completed horn on a line corresponding to line 88 of Fi VI.

n the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are 'taken looking inthe direction of. the little arrows at the ends of the section lines.

Referring to the drawing, the cabinet 1, illustrated, is made up of suitable corner posts, cross pieces and panels. As these de talls form no part of my present invention they are not further, described herein. The cabinet has a hinged top 2 affording-access to the record table 3 and tone arm 4 which may be of any suitable structure.

The motor, shown conventionally at 5, is mounted on the under side of the motor board 6. The motor board 6 has an opening? therein with which the tone arm registers and below this opening is a block 8 having an o ening therein registering with the openmg My improved horn comprises an outwardly flared bell portion and a curved neck portion. The horn is provided with a flange 9 at the end of its neck which is secured to the block 8 on the motor board by means of the screws 10 so that the horn isrigidly mounted'by means of the flange.

A rubber gasket 11 is arranged between the flange and its support to prevent transmission' of. vibrations of the motor board to the horn.

ljhe sounding board 12 is mounted in the cabinet in a spaced relation to the motor board, providing a chamber for the horn. the sound board constituting the bottom of this chamber. pprted at its front. and rear ends on1y,see igs. II and IV. Below the sounding board is a dead air chamber 13, the sounding board gonstituting th top Of this dead air cham- The sounding board is sup The sound opening 14:- of the cabinet is, in

the structure illustrated, provided with an ornamental grid 15. he horn is supported with its enc close to this sound opening, the sound opening, however, being of less dimension than the diameter of the mouth o,f the horn so that the dgflsaof the sound openin project in front of the edges of the neck portions of the horn are preferably rectangularas illustrated.

The side walls 16 of the bell and neck portion of the horn are formed of soft open grained wood disposed'with the grain longitudin'ally' of the horn as indicated in Fig. I. Each side wall is referablyformed integrally of a piece of board cut wood. ,The top and bottom walls are formed ofsections, the outer sections 17 and 18, respectively, extendin substantially to the curve of the horn. T iese outer sections are also formed of soft open grained wood disposed with the grain longitudinally of the horn. The curved neck portions of the top walls, in the structure illustrated, are formed of; relatively short sections 19 20, 21 and 22,while the curved bottom wall is formed ofrelatively short sections 23, 24 and 25, the sectionsbeing disposed edgetoedge and rigidly secured by glue, the edges beiii 'preferablybeveled as shown in Fig. VII These short sections are formed of soft open grained wood and hard close grained wood isposed alternately with the. grain of'the wood diagonally and the grain of adjacent sections alternating in direction as indicated in Figs. II, VI andVII. With the sections as shown in the-drawing the sections 19, 21 and 24 are of soft wood and the sections 20, 22, 23 and 25 are of hard wood.

- I also provide the horn with a coating 26,see Fig. VIII, of hard varnish laid on so as to provide a substantially thick body at the curve of the neck tapering or di-- minishing in thickness toward each end of the horn. This coating is formed by cutting the gum with an alcoholic spirit sufficient to permit'its bein applied in repeated coats to build up the-su stantial body as indicated and to thin it down toward each end into the varnishing coat with which the bell of the horn is preferably provided.

A hollow woodstraight grain post 27 is arranged within the horn restin bottom wall section18 and engaging the top wall at the inner end of-the outer top wall section 17.

I also provide a sound, straight grain post with the horn sufiiciently to maintain 'it in position and perform its function would, of

course, serve in a measure as a support, but

the horn is rigidly supported when this post is removed.

The post within the horn is found toma- 'tion.

I have not attempted to 's'et forth herein my theory of the action ref the various elements or their combined actionwhereby the results stated are reproduced, as such theory,

seems unimportant to an understanding of nd the practical application of my invention.
